GLUE-POT.

Specification of Letters Patent.

Patented Deco 9., 1919.,

Application filed March 29, 1918. Serial No. 225,420.

To all whom it may concern:

Be it known that I, EDWIN G. STAUDE, a citizen of the United States,resident of Minneapolis, county of Hennepin, State; of Minnesota, haveinvented certain new and useful Improvements in- Glue Pots, of which thefollowing is a specification.

The object of my invention is, to provide a glue pot of simpleconstruction and one which can be easily taken apart for cleaningpurposes and which has no narrow or contracted passages or dischargeports in which the glue may dry and clog.

A further object is to provide improved means for mounting the glue potto the end that the glue therein may be uniformly delivered to therolls.

Other objects of the invention will appear from the following detaileddescription.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a plan view of a glue pot embodying my invention,

Fig. 2 is a sectional view of the same,

Fig. 3 is a, cross sectional view,

Fig. 4: is a detail sectional view.

In the drawing, 2 represents a frame of any suitable construction uponwhich are mounted brackets 3, having bearings 4 for a hollow drive shaft5. Piv-oted on the bearings 1 are arms 6 provided with bearings for ashaft 7. The arms 6 are secured to the frame 2 of the machine by meansof bolts 8 passing through lugs 9 in the arms and having lock-nuts 10for adjustment of the lugs on the bolts. Secured to the arms 6 arebrackets 11 provided with adjustable bearings 12 for a shaft 13.

The shafts 5, 7 and 13 are provided with rolls 14, 15 and 16. The rolls14 and 16 serve as a bottom for the glue pot 17. The paste on the roll16 is applied to the roll 15 which is preferably provided w1th a coverof rubber or other suitable material. The paste accumulated on therubber cover of the roll 15 is applied to the surface of the box coveror other article coming in contact with this -roll. In this instancev Ihave shown the glue being applied to a box cover 18 on a form 19 passingunderneath the-glue roll 15. The roll 14 serves as a means for spreadingand thinning the paste or glue of the roll 16. The adjustment betweenthe two rolls can be made in the brackets 11.

The glue pot is formed of ends 20 and the front and rear walls 21 and 22fitting into grooves 23 in the ends and secured by means of rods 24. Theends have slots 25 and 26 to straddle the hubs of the rolls l4: and 16.The whole pot can be lifted up and cleaned and permit easy access to therolls for cleaning. The paste or glueis comparatively thick and as therolls lat and 16 are working toward each other, there is no danger ofany paste working down the side walls.

To drive the rolls, I secure to the shaft 5 a collar 27 and a pin 28 ona collar 29 has a sliding connection in the collar 27 and projects intothe path of a pin 30 on the hub of the sprocket 31 that is driventhrough suitable chain, not shown. To release the pin 28 and stop theshaft 5 from revolving I provide within said shaft a rod 32 secured tothe collar 29. The opposite end of the rod has a hand grip 33. lVhencversaid rod is pushed forward the pin 28 is pulled out and the shaftstopped. A suitable hand wheel 31 is provided on the shaft.

The power is transmitted from' the shaft 5 to the shaft 13 through gears35 and 36 and to the shaft 7 through gears 37 and 38. The rolls 14 and15travel at the same speed, but the roll 16 travels slower. The roll 14:acts as a scraper on the roll 16 and the roll 16, traveling slower thanthe roll 15 and in the opposite direction, will deposit paste on thesurface of the roller 15 in a thin, even layer.

The glue pot, as shown in Fig. 2, has

bearings on the ends of the rollers, the joint.

being sufliciently close to prevent the glue from working down betweenthe walls of the pot and the roll, while permitting the roll to revolveand spread the glue thereon. The opening in the bottom of the pot beingthe full size thereof, it is evident that there will be no opportunityfor the glue to dry and accumulate or clog therein. Vhenever desired,the pot may be removed and the inner surface of the walls thereof andthe surfaces of the rolls cleaned.

In various ways the details of construction may be modified and still bewithin the scope of my invention.

I claim as my invention:

1. The combination, with the glue rolls, of a glue pot adapted tocontain'an adhesive and having an open bottom seated on said rolls, theperipheral surfaces. of said rolls forming the bottom of said potandreceiving the adhesive therefrom.

2. The combination, with the rolls having hubs, of a pot having wallsfor straddling said' hubs, said pot being open at the bottom and saidrolls normall closing the same' and receiving the materlal therefrom,the opening in the bottom of said pot being equal to the full transversearea of the pot, whereby freedom of discharge of the glue is permitted.

3. The combination, .with the glue-sup porting rolls, of a glue potmounted thereon and comprising side and end walls bolted together forconvenience of separation, said pot being removably mounted on the hubsof said rolls.

l. The combination, with the glue rolls, of a glue pot comprising sideand end walls, said side walls having vertical grooves therein toreceive the edges of said end Walls, and bolts for securing said wallstogether, said glue pot having an open bottom, the glue being supportedin said pot upon the peripheral surfaces of said rolls.

5. The combination, with a pair of rolls revolving toward each other andmeans for adjusting the space between said rolls, of a receptacle forholding adhesives mounted above said rolls, said receptacle beingadapted to permit the said whole body of adhesive to rest directly onsaid rolls by gravity to allow the feeding of a non-flowing adhesivebetween said rolls in a continuous sheet.

6. The combination, with the rolls mounted to revolve toward each other,of a bottomless receptacle adaptecl to contain an adhesive substance andsupported above said rolls, the peripheries of said rolls closing theopen bottom of said receptacle and forming a support for the adhesivematerial in said receptacle, the revolution of said rolls feeding theadhesive between them.

7. The combination, with a pair of rolls revolving toward each other andmeans for adjusting the'space between said rolls, of a receptacle forholding adhesives mounted A above said rolls, said receptacle beingadapted to permit the said adhesive to rest directly on said rolls bygravity to allow the feeding of non-flowing adhesive betweensaid rollsin a continuous sheet.

In witness whereof, I have hereunto set my hand this 14th day of March,1918.
